Incumbents Leverage Scale Against Arc
Arc
Arc’s manufacturing edge is most fragile where incumbents are strongest, in building boats cheaply and at volume. Arc controls its own hulls, battery packs, and power electronics, which helps it tune performance and save roughly 50 percent on battery material costs versus off the shelf systems. But legacy builders already own factories, supplier terms, dealer lots, and service shops, so once electric drivetrains are good enough, they can spread those parts across far more units and close the gap fast.

Arc sells finished boats directly and also builds commercial tug drivetrains, which means it has to solve fiberglass or aluminum hull production, battery assembly, charging, service, and customer delivery all at once. Incumbents can keep their existing hulls and channels, then swap in electric propulsion from suppliers like Mercury Avator, Vision Marine, or Evoy.

That is why supplier specialists matter. Vision Marine and Evoy let established brands add electric power without inventing batteries and motors from scratch. Brunswick pushes the same logic through Mercury Avator, using existing dealer and service networks to make electric boats easier to buy and maintain than a new standalone brand.

There is already a template for this kind of scale advantage. Candela built distinctive hydrofoil technology, then partnered with Groupe Beneteau to scale production. The broader pattern is that novel electric or efficiency technology often starts in a startup, then reaches wider markets faster when paired with an incumbent manufacturer’s purchasing power and factory footprint.
The next phase of competition is likely to shift from raw performance to delivered cost, service coverage, and production speed. If battery prices keep falling and electric propulsion modules become more standardized, the winners in marine electrification will increasingly be the companies that can turn proven components into reliable boats at scale, not just the ones that engineered them first.
